Click the Erase button, which brings up another window, where you.Choose the indented one that shows an eject button. select the WD My Passport entry on the left-side.

You can find that either in the Applications folder (probably within the Utilities sub-folder) or just search for it using the magnifying glass icon at the top-right of your screen. Plug the drive into your Mac and run the Disc Utility app. You can also use the Disc Utility app to format the new My Passport. So it might not be worth the effort in your case.

My Passport drives come with both Windows and OS X utilities for generic backup, but your Mac’s Time Machine app is a much better way to backup your Mac. The My Passport drive comes with a few utilities already installed on it, and if you want to save them, copy them to your Mac’s hard drive before you erase the disk. The hardware is identical inside, and any My Passport can be easily formatted for use with either a Mac or a Windows PC. You can buy drives already pre-formatted for a Mac, but I’ve found the one’s like you bought to be less expensive.
#My passport for mac is pullged in bt i cant find my backups for mac os x#
In order for the Mac to use it, it has to reformat it for Mac OS X (Journaled). What probably happened is that when you purchased the My Passport you actually bought one that was pre-formatted for a Windows PC.

Short answer, go ahead and click the Erase button, which will reformat your My Passport drive to be used on your Mac. When I plugged it in and tried to set it up in Time Machine, I got a warning “Are you sure you want to erase the backup disk “My Passport”? Erasing will destroy all information on the disk and can be undone.” Should I go ahead or did I miss something? I want to use it with my MacBook Pro which has El Capitan on it, with the Time Machine app. I just got a new My Passport 2tb external storage drive from Staples.
